JOURNAL-Box.

SPECIFICATION forming part of Letters Patent No. 269,714, dated December26, 1882 Application filed July 17, 1882. (Model.) i i A To all 'whom itmay concern:

shown in full elevation.

Be it known that I, LEVI H. RoBEn'rs, of Paris, in the county oi' Edgarand State of Illinois, have invented certain new and useful Improvementsin Journal-Boxes, ot' which the following is a full, clear, and exactdescription.

rlhe object of this invention is to provide a practical anti-frictionjournal or axle box for railroad-car and other axles or shafts; Aand itconsists principally ofjournaling two anti-fric tion wheels or rollersin and between two (front and rear) boxes, whichare coupled together andadaptedto receive or to be placed upon the .journal portion of the axle,with the anti-friction wheels or rollers resting upon the axle andsupporting the weight ofthe car or other load.

The invention also consists of triangular oilboxes for the journals ot'the antifriction wheels or rollers, of the means for coupling the saidfront and rear boxes together, and of suitable journal-blocks to tit inthe front. and rear boxes upon the journals of the antifriction wheels.

Reference is to be had to the accompanying drawings, forming part ofthis specifica-tion, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a broken elevation of the rear face ot' the rear box,showing the axle of the car in section. Fig. 2 is a broken elevation ot'the front face ot' the front box. Fig. 3 is a broken elevation of theinner face of the front box, showing the axle of the car and the outsidejournal of one of the anti-friction wheels in section, the outeranti-friction wheel being Fig. 4 is a transverse sectional elevation ofthe complete axle-box, part being broken away to show the dust plate orslides of the journals vof one of the antifriction wheels. Fig. 5 is afront elevation of one ofthe dust-plates removed fromits slot or recessin the box. Fig. 6 is a perspective view are in place in the boxes G C',or rather when these boxes are in place upon the journals ot the wheels,the wheels are held in place by the journal-blocks D D, which areplacedin the boxes and lit upon the journals between the lla-tiges c andbosses c'. These journal-blocks are made preferably of brass and castwith the ribs d', are segmental in form, and are held in placein theboxes and upon thejournals b b ot' the wheels by the shelves or ledges EE and recess d", formed upon the inside of the boxes, as shown in Fig.2.

The front and rear boxes, C C', are in all essential particularsduplicates ofeach other, except that the rear box, C', is formed vwithpassages c a through the walls thereof for the passage of the axle A,while the front box, (l, is formed with the thrust box or recess E toreceive or lit over the outer end ot' the axle, as shown in Fig. 4, andthat the outer or rear wall of the box G is made double or formed withthe passage d, as shown in Fig. 4. In this passage d is placed the dustplate or slide f, which surrounds the axle A and closes the passage a'in the rear Wall of the rear box,C, as shown, and this plate issupported by the axle which it protects, and thekpassage d is of suclheight asto permit it to move up or down with the axle. with any upwardmotion of the car, and the plate is of such size as to perfectly closetbe passage c at all times.

The inner Wall ofthe front box, C, and also the inner wall of the rearbox, C', are made double or formed with the recessesjj andjj'.- In therecesses j j are placed the dust plates or slides g g, and in therecessesjj are placed similar dust plates or slides, g g, as sh'owninFig. 4. l These plates it upon the bosses c c' of the journals' of thefriction-rollers B B, as

IOO

shown in Fig. 4, and close perfectly the openingsk kin the inner wallsof the boxes, through which thejournals ofthe wheels B B pass, asindicated in said figure, and thus prevent altogether the entrance ofdust into the oilboxes F F, in which the journals b b ot' the wheels B Brun.

G G represent plates which rise diagonally from the lower side or bottomot` the boxes U C', and form a V-shaped partition in the center oftheboxes, as shown in Figs. 2 and 4. These plates give the oil-boxes F Ftriangular form, as will be understood from Fig. 2, so that the wasteput in the oil-boxes will be forced nearer to and kept in contactwiththe journals -b b as it sinks gradually to the bottom of the boxes.

The oil-boxes are closed by the covers H H, and these covers are formedupon the under side and near the ends with the ribs or downwardprojections ll, which, when the covers are in place, come in front ofthejournal-blocks l) D and prevent them from getting out.ot' place, aswill be understood from Figs. l and 2. The front and rear boxes, C C',are preferably coupled together by means of the upper and lower plates,K K, upper and lower outside clainp-plates, L L, end plates, M M, U-bolts N N, and cross-plates O O, as shown in Fig. 6. rlhe upper andlower plates, K K, are correspondingly guttered upon the inside, asshown at o o, to receive the lips p 1J, formed at the upper and loweredgesot' the boxes,and the side plates, M M, are also correspondinglyguttercd, as shown at 0 o in Fig. 6, to receive the lips pp, formed atthe outer edges of the said boxes, as shown in Figs. 1 and 2; and

Y upon the outside and at the ends of these side plates are formed theclaws q q, which retain the U-bolts N N, as shown in Fig. 6.

Along the outside of the plates K K are formed the gutters q' q', inwhich the outside clamp plates, L L, rest, as shown in Fig. 4, whichprevent all danger of lateral movement ot' the plates K K.

All ot' the parts of the journal-box having been put in place, thecross-plates 0 0 are put upon the U-bolts N N, and the nuts s s are thenturned upon the threaded ends of the said bolts, and thus clamp all theparts firmly and securely together.

In Fig. 7 plain bolts NN are used in place of the U-bolts N N. Whenthese bolts are used, instead ot' forming the end plates, M M, with theclaws q q, these plates will be formed with the bolt-passages t t,through which the bolts Nl N pass, as shown in said Fig. 7.

The passagesjj and j j are made wider at the top than at the bottoni,but straight on the inner edges, as indicated in dotted lines in Fig.l3, so that the plates will be free to move upward as the journal-blocksD D wear away, but not toward the center. The outer end of the axle A isformed with the central projectioinv, as shown in Fig. 4, which receivesthe side-thrust of the axle against the wall of the thrust-box E', thusgreatly reducing the friction and the outer ends of the journals b b ofthe anti-friction wheels B B are formed with the central projections,ofv, as shown in said figure, to receive. the side-thrust against theouter walls ofthe boxes G C.

T is a truss-band placed around the outer end of thefrontbox, C, and Tis asimilar band placed around the rear end of the rear box, C', asshown in Fig. 4, for reenforcing the boxes and protecting them at theouter edges.

By this construction of the axle-boxes it will be seen that the frictionand journal motion in the boxes will be greatly reduced, thus increasingthe capacity of the motive power and preventing all danger of boxesbecoming heated. Besides, the boxes are strong and durable.

Having thus fully described my invention,I claim as new and desire tosecure by Letters Patent- 1. The front and rear boxes, O C', incombination with the anti-friction wheels B B, journaled in and betweenthem, the said boxes being coupled together, substantially as and forthe purposes set forth.
